Starrett 190A: The Ultimate Guide to Screw Jacks

screw jack

A screw jack is a device used to lift heavy loads. The Starrett 190A is one of the most popular screw jacks in the market. In this guide, we will look at its features, uses, working principle, and how it differs from hydraulic jacks. We will also learn how to choose the right screw jack for your needs.

What is a Screw Jack Used For?

There are several uses of screw jacks:

1. Lifting Heavy Loads

Screw jacks are used to lift heavy loads in various industries, including construction, automotive, and manufacturing. The Starrett 190A has a lifting capacity of up to 10 tons, making it suitable for heavy-duty applications.

2. Positioning Equipment

Screw jacks are also used to position equipment, such as machine tools and conveyors. The Starrett 190A has a precision screw and nut, which allows for accurate positioning.

3. Leveling Structures

Screw jacks can be used to level structures, such as buildings and bridges. The Starrett 190A has a unique worm gear design, which provides smooth and stable lifting.

What is the Working Principle of Screw Jack?

The working principle of a screw jack is based on the concept of a screw and nut. When the handle is turned, the screw rotates, and the nut moves along the screw, causing the load to be lifted or lowered. The Starrett 190A has a precision screw and nut, which provides smooth and efficient operation.

There are several factors that affect the performance of a screw jack:

1. Lead

The lead is the distance traveled by the nut for one complete turn of the screw. The lead determines the lifting speed and efficiency of the screw jack. The Starrett 190A has a lead of 5/16 inches, which provides fast and efficient lifting.

2. Pitch

The pitch is the distance between adjacent threads on the screw. The pitch determines the mechanical advantage and lifting capacity of the screw jack. The Starrett 190A has a pitch of 2.5 inches, which provides high lifting capacity.

3. Load Capacity

The load capacity is the maximum weight that the screw jack can lift. The Starrett 190A has a load capacity of up to 10 tons, making it suitable for heavy-duty applications.

4. Material

The material of the screw and nut affects the durability and performance of the screw jack. The Starrett 190A has a screw and nut made of high-strength steel, which provides long-lasting performance.

What is the Difference Between a Screw Jack and a Hydraulic Jack?

A screw jack and a hydraulic jack are both used to lift heavy loads, but they work on different principles. A screw jack operates on the principle of a screw and nut, while a hydraulic jack operates on the principle of hydraulic pressure.

There are several differences between a screw jack and a hydraulic jack:

1. Operation

A screw jack is operated by turning a handle, while a hydraulic jack is operated by pumping hydraulic fluid into a chamber.

2. Speed

A hydraulic jack provides faster lifting than a screw jack, but it requires more maintenance and can be more expensive.

3. Capacity

A hydraulic jack can lift heavier loads than a screw jack, but it requires a larger footprint and more space.

Choosing the Right Screw Jack

When choosing a screw jack, there are several factors to consider:

1. Load Capacity

You should choose a screw jack with a load capacity that is suitable for your application. The Starrett 190A has a load capacity of up to 10 tons, making it suitable for heavy-duty applications.

2. Lift Height

You should choose a screw jack with a lift height that is suitable for your application. The Starrett 190A has a lift height of up to 13 inches, making it suitable for various applications.

3. Lead

You should choose a screw jack with a lead that provides the desired lifting speed and efficiency. The Starrett 190A has a lead of 5/16 inches, which provides fast and efficient lifting.

4. Pitch

You should choose a screw jack with a pitch that provides the desired mechanical advantage and lifting capacity. The Starrett 190A has a pitch of 2.5 inches, which provides high lifting capacity.

5. Material

You should choose a screw jack with a screw and nut made of high-strength steel for long-lasting performance. The Starrett 190A has a screw and nut made of high-strength steel, providing long-lasting performance.
